Final answer:
The correct answer is A. Continue in the same direction, continue at the same speed, and come to a stop are not always true when unbalanced forces are present.
object subjected to unbalanced forces will always accelerate, as explained by Newton's second law of motion. This happens because the unbalanced forces create a net force on the object, causing a change in its velocity, either by speeding up, slowing down, or changing direction.
Step-by-step explanation:
When an object is acted on by unbalanced forces, it will always accelerate. This is explained by Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. Thus, if unbalanced forces are acting on an object, there is a net force causing the object to accelerate.
Examples of Unbalanced Forces and Acceleration
- A car speeding up when the gas pedal is pressed.
- A ball falling to the ground due to gravity (if we ignore air resistance).
- An object slowing down because of friction (when there is no opposing force).
Therefore, the correct answer is A. Continue in the same direction, continue at the same speed, and come to a stop are not always true when unbalanced forces are present.
